From 8b7a24e20f345cccf407ddc9a8133d75fdc99448 Mon Sep 17 00:00:00 2001 From: Laurent Pinchart Date: Mon, 29 Apr 2019 15:03:24 +0300 Subject: meson: Link against libc++ with compiling with clang MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit libc++ is used by Chrome OS, and likely as well by other environments based on clang. Using it by default if available when compiling with clang will help extending the compile-testing coverage. The drawback is that issues specific to clang with libstdc++ will not be caught as easily, but based on the experience with clang so far, code compiling correctly with gcc/libstdc++ has failed with clang due to either clang-specific or libc++-specific behaviour, never due only to the combination of clang with libstdc++.
